Bcrypt is a cross platform file encryption utility. Encrypted files are portable across all supported operating systems and processors. Passphrases must be between 8 and 56 characters and are hashed internally to a 448 bit key. However, all characters supplied are significant. The stronger your passphrase, the more secure your data.
The 2048-bit is about the RSA key pair: RSA keys are mathematical objects which include a big integer, and a "2048-bit key" is a key such that the big integer is larger than 2 2047 but smaller than 2 2048.. The 256-bit is about SSL. Even though 448-bit encoding is extremely big digit and comes with more security and safety but to be fair, AES 256-bit has faced more testing as compared to 448-bit encoding. It is advised to use industry proven standard of AES 256-bit encryption so, it would be stupid to move to another encryption standard just because it sounds better. Blowfish is a variable-length key, 64-bit block cipher. The algorithm consists of two parts: a key-expansion part and a data- encryption part. Key expansion converts a key of at most 448 bits into several subkey arrays totaling 4168 bytes. Data encryption occurs via a 16-round Feistel network. Cypherix® announces the release of Cryptainer LE (12.0 series), the free 448 bit encryption software. Cryptainer LE encrypts any type of data on any Windows PC on any kind of media. Specially tailored to answer security and privacy needs of the average PC, Cryptainer LE combines ease of use and simple drag-and-drop operations. Blowfish is a 16 round feistel chiper that has key lenght from 32 to 448-bit and use large key dependent s boxes. Blowfish is similar to Cast 128 structuraly. In blowfish, every line represents 32 bits. Two subkey arrays are kept the 18 entry P-array and four 256-entry S boxes, which takes 8 bit input while producing 32 bit output.

Marx 448 Bit Encryption v2.0 uses blowfish with a full strength 448 Bit key and the Tiger Hashing Algorithm to ensure file integrity. This new version has a redesigned interface that makes the The key size is between 32 and 448 bits, with 448 bits obviously being the strongest encryption. It is considered very good for smaller amounts of data (like e-mails etc.), but becomes less good with very large amounts of data (several GB's) because of the relatively small block size (64 bits) used in the cipher. Marx 448 Bit Encryption is designed around the Blowfish Encryption Algorithm and the Tiger Hashing Algorithm. Both algorithms are in the public domain and have been tested time and time again. It takes a variable-length key, from 32 bits to 448 bits, making it ideal for both domestic and exportable use. Blowfish was designed in 1993 by Bruce Schneier as a fast, free alternative to existing encryption algorithms. Since then it has been analyzed considerably, and it is slowly gaining acceptance as a strong encryption algorithm. But I would like to point out AES-256 is only for PROe version (which now called Code42 CrashPlan, confusing), which is only for enterprise with 100+ computers. So it is not possible/affordable even if a small business wants to upgrade their encryption. Both CrashPlan for Home and CrashPlan PRO (business) are 448-bit Blowfish.
